WATER-H EATER.

SPECIFICATION forming part of Letters Patent IVO. 544,019, dated August6, 1895..

Application filed May 8, 1894. Serial No. 510,521. (No model.)

To all whom t may concern,.-

Be it known that we, GEORGE VILsON and SAMUEL BERNSTEIN, citizens f theUnited States, residing at Chicago, in the county of Cook and StateofIllinois, have invented a new and useful Improvement in- Water-Heaters,of which the following is a specification.

Our invention relates to an improvement in the class of heaterswhich'have come to be known in the art as instantaneous water-l heaters'and are designed for heating water while it courses through theapparatus, especially for bath purposes, on merely igniting a suitableburner at the base of the heater and turning into the latter thecold-water supply.

Our present improvement in the features of its general constructionpartakes of the nature of that set forth in Letters Patent of the UnitedStates No. 429,300, granted to Samuel Bernstein, one of the presentapplicants, on

the 3d day of June, 1890.

The objects of our improvement are to provide for preparatorily warmingthe water admitted to the apparatus in its course therein to thespraying mechanism, which serves to impinge it in a finely-dividedcondition upon the heat-imparting surfaces in the heater and whichdirect it to the discharge, to provide for utilizing the steam generatedby the operation of the apparatus to commingle with and exert itsdeodorizing effect on the products of combustion from the burner, and toimprove the construction of the apparatus generally and in matters ofdetail, the better to adapt it for its rapidheating function.

Referring to the accompanying drawings, Figure l represents our improvedWaterheater by a view in vertical central sectional elevation with thesupply and outlet pipe details' shown broken. Fig. 2 is a View inelevation of the inner spiral-liangc-carrying shell of the jacketenveloping the heater. Fig. 3 is a plan view of the spraying-head. Fig.4 is asimilar view of the distributing-head. Fig. 5 is a plan view ofthe yoke for conducting the water-supply which enters thedistributing-head to the spraying-head, and Fig. 6 is a broken viewshowing the feed-pipe deflector detail. A f

A is the base of the apparatus, preferably of cylindrical shape, formedof sheet metal, and provided with numerous perforations to admit air tothe burner B, supported in the base, and whichA may be of theconstruction represented or of any other suitable construction. Asillustrated, the burner comprises an annular. chamber r, supported inhorizontal position in the base A and perforated in its upper side, asat x, the opening in the annulus containing an annular burner-head q,communicating with the chamber fr through a threaded coupling r',whichsupports-in its position the head q, the latter being .perforated,as at zo', in its upper side and covered by a perforatedplate p.

The burner B, which forms no part of our invention, being old andtherefore not illustrated'in all its minordetails, is adapted forheating by gas as the fuel, and to that end has a pipe o ofcomparatively-large diameterleading at one end into the annular chamberfr,

the opposite end being in the form of a funnel o', the more readily todraw in air with the gas, which is supplied by the pipe rrz, providedwith suitable shut-off-valve mechanism.

vOn the upper edge of the base A is seated a water-jacket C, preferablyof the illustrated cylindrical shape as to its body portion, with anexpanded base portion m, closed about its lower edge, and a contractedupper end m. The jacket C is formed with two concentric similarly-shapedsheet-metal shells Z and Z', affording the annular space Zi or chamberbetween them, the course through which, from the point in the base m atwhich the coldwater supply-pipe la enters the space, is ren- V,deredspiral by a spiral flange Z3, extending about the outer surface of theinner shell Z from near its lower end nearly to the contracted upperend, the spiral` ange extending entirely or nearly across the chamberZ2. The jacket C envelops a vertical cylindrical or tubular sheet-metalshell C', surmounting the central portion of the burner B and containingan upwardly-tapering sheetmetal shell C2, fastened or sealed about itslower flaring edge to the adjacent inner edge of the shell C andsurrounded near its upper end by the annular spraying-head D, whichseats on an offset or corrugation t', formed in the IOO shell C. Thespraying-head is corrugated or serrated, as shown at e o', respectively,about its periphery and central opening to afford numerous smallopenings. On an annular diaphragm 7L, in which the upper tapering endofthe shell C2is fastened or sealed, are secured the two hollow legs g(to coincide with openings t in the diaphragm) of a yoke E, the hollowbody g of which, and from x o which the legs proceed, supports adisk-shaped baille-plate F for the products of combustion passingthrough the shell C2, and is connected by a screw-coupling e with anannular distributing-head F, into thelower side of which the contractedend of the jacket C enters, the head F, which thus crowns thewater-jacket, having three internal radial branches e', which open intothe coupling e.

From the base of the upwardly-flaring wazo ter-chamber G, formed betweenthe shells C and C2, proceeds the outlet-pipe d to a hollow head d,(shown cone-shaped,) and fromn the lower end of which extends thedraw-oft pipe d2, provided with a suitable valve; and from the upper endof the head d extends a valvecontrolled pipe d3, through the jacket Cinto the annular space s between the jacket and shell C', for theproducts of combustion from the burner-openings at.

The heater is surmounted by a suitably-ornamented cap H.

The operation is as follows: Upon turning on the gas to the burner andlighting it, so that the products of combustion pass upward through theshell C2 and space s, escaping through the cap II,at`ter having impartedtheir heat to the surrounding surfaces in the mitted from the pipe 7ainto the jacket C, be-

40 ing directed therein by a defiector 7a' at the inlet to follow in thedirection of the arrow in Fig. 2 the spiral course about the chamber Z2,

whereby itis preparatorily warmed on its way to the distributing-head F,from which it is directed through the branches e and coupling e into theyoke E and bythe legs g of the latter upon the spraying-head D. To

leave the spraying-head, the water must pass through the small openingsafforded by the 5o serrations o and e', which direct it in finelydividedcondition into thechamber G, wherein it contacts with the surfaces ofthe intensely-heated shells C and C2, and in coursing down the latterbecomes hot. In discharging the hot water when boiling through the piped2, the valve in the pipe d3 should be open to admit the steam, whichpasses with the water from the chamber G into the head d, to

the annular iue or passage s therein to como mingle with the products ofcombustion and exert its deodorizing effect thereon.

Vile show in Fig. l an extension d4 of' the pipe dprovided with ashut-off Valve and intended to lead to a shower, (not shown,) and to beused with the valves inthe pipes d2 and d3 closed. It may be stated,however, that in practice the apparatus is not intended to beconvertible from a shower to a bath-tub-filling device or vice versa, sothat when itis to be used for the first-named purpose the head d andpipes d2 and d3 may be omitted, the pipes d4 and d' then beingcontinuous or one and the same pipe, as indicated by dotted lines, andwhere it is to be used for the lastnamed purpose the pipe d will beomitted.
